I own a good chunk of land that used to be an old mining camp back in the day. The stamp mill sat for 71 years operating in one location next to the river. I know I have found alot of mercury leaching from where the stamp mill was when I dredged just below it. I can flood the area and dredge where it sat just curious if it would be worth doing. Heres a pic. The cam to the mill is in the middle of the river. that area made a large bowl like area in the canyon. could be some good stuff down at the bottom. Any Inputs??
